Verify AI work, keep the proof

Only for iPhone

PortMem checks work written about documents, and keeps proof that the check happened. Give it the documents that govern a matter: the credit agreement, the filing, the label, the policy. Then give it a report written about them, whether a person wrote it or a model did. PortMem reads every claim in the report back against the source and tells you three things. Which claims the documents support. Which they contradict or fail to support. And what the report left out. Nothing is delivered on the machine's say-so. Every flagged claim shows the passage it was judged against, so you can decide for yourself, and you sign it off with a reason in your own words. The report is held at a gate until you do. What you are left with is a record. Each sign-off is written to a hash-chained ledger, so a later change to it is detectable. You can publish a verification page for a review, or export a signed evidence packet that someone else can check independently, offline, without PortMem. IN THE APP Review: pick the governing documents, paste a report or hand it a file, and run the review. Evidence: every verdict shows the source passage behind it. Omissions: what the documents cover and the report does not. Sign-off: approve or reject claim by claim, with a reason, recorded in the ledger. Documents: upload from Files, delete what you no longer need, and confirm when a new upload amends one you already had. Records: the ledger, with chain verification. Notifications: a long review takes minutes. Turn them on and your phone tells you when the gate holds or clears. WHO IT IS FOR People who have to be able to show their work. Credit and legal teams reading agreements. Regulatory teams reading labels and filings. Anyone signing their name under something a model helped write. YOUR DATA Your workspace is private to you. Documents, reviews and audit records are isolated per account. The app carries no analytics, no advertising identifier and no third-party tracking. An account is required.

The email PortMem sends when a check you started has finished now opens that check's results right here in the app. Notification settings also say when PortMem emails you instead of notifying your phone.
